- A chromosome is a single DNA strand. On the image you can actually see 2 chromosomes, which means 2 strands. They may be (almost) exact copies if they are the result of a duplication during mitosis or meiosis, or they may be different homologous chromosomes joined together during meisosis; it’s hard tot ell without further context.

- Each strand can therefore serve as a template, or mold, for the synthesis of a new complementary strand. In other words, if we designate the two DNA strands as S and S ʹ, strand S can serve as a template for making a new strand S ʹ, while strand S ʹ can serve as a template for making a new strand S (Figure 6–2).

- chromosome-a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order; humans have 22 chromosome pairs plus two sex chromosomes.. A linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. 2. A circular strand of DNA in bacteria and archaea that contains the hereditary information necessary for cell life.

Difference Between Gene and Chromosome Chromosome is an organized structure in cells containing a long, coiled, and single strand of DNA with some associated proteins. A chromosome is a long DNA strand or molecule that includes a number of genes, regulatory elements, and nucleotide sequences.herefore, it could be said that chromosomes are longer and larger than genes. • Chromosomes carry genes but not the other way around. • Gene is composed of only serially connected nucleotides while chromosome has nucleotides and proteins in the structure.

What is a chromosome? DNA and histone proteins are packaged into structures called chromosomes. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes.

What are the differences between chromosomes, chromatids and chromatin? A chromosome is a molecule of DNA; a chromatid is a very specific term for a newly-replicated chromosome that is still attached to it's sibling chromosome (one chromosome replicates into two sister chromatids). Once replication and cell division is over, the chromatid reverts to being a plain old chromosome.

Chromosome A chromosome is a single large macromolecule of DNA, and is the basic 'unit' of DNA in a cell. It is a very long, continuous piece of DNA (a single DNA molecule), which contains many genes, regulatory elements and other intervening nucleotide sequences. In some circumstances chromosome also refers to the DNA bound proteins which package and manage the DNA.

Chromosome A chromosome is a structure that occurs within cells and that contains the cell's genetic material. That genetic material, which determines how an organism develops, is a molecule of deoxyribonucleic acid (DNA). A molecule of DNA is a very long, coiled structure that contains many identifiable subunits known as genes. In prokaryotes, or cells without a nucleus, the chromosome is merely a circle of DNA. In eukaryotes, or cells with a distinct nucleus, chromosomes are much more complex in structure. Historical background The terms chromosome and gene were used long before biologists really understood what these structures were.

Chromosome Structure and Function Share. By Regina Bailey. Definition: A chromosome is a long, stringy aggregate of genes that carries heredity information (DNA) and is formed from condensed chromatin. A non-duplicated chromosome is single-stranded and is comprised of a centromere region that connects two arm regions.

- Chromosomes are double strands of DNA and associated histone proteins, evident as stained chromatin within the nucleus of a eukaryotic cell. Chromosomes become distinct during cell division (mitosis/meiosis), when they become tightly coiled.

- A chromosome (chromo- + -some) is a packaged and organized structure containing most of the DNA of a living organism.uman cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. In addition to these, human cells have many hundreds of copies of the mitochondrial genome.

Coding strand Wherever a gene exists on a DNA molecule, one strand is the coding strand (or sense strand or non-template strand), and the other is the noncoding strand (also called the antisense strand, anticoding strand, template strand, or transcribed strand). Strands in transcription bubble

How many DNA strands does a chromosome have? 1 DNA molecule-This means a double helix (2 strands). 1 DNA strand-This means when you break the double helix and one separate strand. I thought one chromatid contain 1 DNA strand and 2 chromatids make a chromosome and 1 DNA molecule.

What is a chromosome made up of? A chromosome is made up of tightly-packed structures called DNA. Each DNA is made up of nucleotides. Each nucleotide is made up of a sugar, a phosphate, and a base (adenine, cytosine, guanine, and thymine).

Eukaryotic DNA replication A chromosome is a long strand of DNA. At the end of a chromosome is a telomere, which acts like a bookend. Telomeres keep chromosomes protected and prevent them from fusing into rings or binding with other DNA. Telomeres play an important role in cell division. Each time a cell divides, the DNA unwraps and the information in the DNA is copied.

MADMAN BIOLOGY Actually, when we talk about strands of DNA, this can refer to DNA molecules of any length (measured in single A,T,G, or C nucleotides known as base pairs). Human cells contain two sets of 23 chromosomes, one set inherited from each parent (46 total).

What are chromosomes made of? What is a chromosome? In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope.

- 1. When does DNA replication take place in the cell cycle? 2. When do strands of DNA form chromosomes? 3. What is a replicated chromosome? How does this differ from a chromosome pair? 4. Is a cell containing replicated chromosomes haploid, diploid, or neither? Why? 5. Why is anaphase important and unique in terms of chromosome number? Students should use a minimum of three scholarly sources with valid URL. Remember that Wikipedia is not considered a scholarly source.

What is the name of the point at which the two halves of duplicated chromosomes are connected? A duplicated chromosome is formed as a result of DNA replication. Since DNA replication is semi-conservative, the two components (or strands) that.

What Is the Difference Between Chromosomes and Genes? In a chromosome, the DNA is tightly packed together with histone proteins. If all the DNA strands in the human body were laid end to end, they would form a very thin strand about 6 billion miles long. The complexity of the organism usually predicts the number of genes and chromosomes.

- During DNA replication both strands of the DNA are reproduced, so D is out as an answer. Yes, a complementary strand of DNA is reproduced, but this answer suggests that only one strand of DNA is made when in fact two strands of DNA are made.
